I heard that for some subjects the difference between the HL and SL course was huge (where the HL course was much much more demanding and the test was more difficult), while for other subjects the difference between the HL and SL level course was small (so students are better off taking the HL course since they are almost similar).
Which courses have big difference between HL/SL and which courses don't?
